adbon your PATH.

}
Your first run
Android
The repo ships a working sample at examples/folio, a Kotlin Multiplatform app with a TypeScript spec under sanderling/spec.ts. Install just, then from examples/folio:
just install # build and install the folio APK on a booted emulator or device
just test # run the spec
With no device connected and multiple AVDs, pick one:
AVD=Pixel_7 just test
Persistent settings can live in a .env alongside the justfile (AVD=Pixel_7, DURATION=5m, and so on).
Web
The repo also ships a web sample at examples/folio-web, a React/Vite app with the same domain logic. From examples/folio-web:
just test # starts Chrome, runs the spec
No emulator or SDK setup needed.
